The major sensory dimensions of the mouthfeel of fruit based beverages were determined by principal components analysis and the degree of correlation between mouthfeel characteristics and the taste and pleasantness of beverages was assessed. Untrained college students rated 35 different beverages on 16 different 10‐point scales containing mouthfeel, taste and hedonic terms. Two major mouthfeel dimensions emerged with this set of beverages and they were termed density/thickness and chemical irritant effect. An interdependence between mouthfeel and taste ratings was also found. Sweetness ratings were negatively correlated and sour, salty and bitter tastes were positively correlated with mouthfeel terms describing oral mucosal irritation.

Testing on a final exam in a college course improved long-term retention over material that had not been tested on the final. Students from an upper level psychology course took a long-term retention test, four to five months after the end of the course. For half of the items, a related question had been on the final. For the remaining half, a related question had appeared on an earlier exam, but not the final. On the long-term retention test, percent correct was 79% when a related question had appeared on the final and 67% when a related question had not appeared on the final. These results have both theoretical and practical implications.

A role-play test was developed to assess the sales skills required for success in a telemarketing job. The 30-minute test was conducted entirely by telephone and consisted of four role-plays in which the ratee attempted to sell a service contract. In a concurrent validation study, the sum of two raters' independent evaluations of overall performance on the four role-plays was significantly correlated with both objective and subjective measures of sales performance. Based on generalizability analyses, the reliability of the overall ratings provided by two raters for four role-plays was .80 in the concurrent study and .76 when the role-play test was used operationally. This study demonstrated that ratings from a 30-minute telephone role-play test are valid and reliable predictors of sales performance.
